Summary

Head and neck squamous cell carcinoma (HNSCC) presents a significant clinical challenge, as over 60% of patients are diagnosed at a locally advanced stage with a high risk of recurrence. Although the landmark KEYNOTE-689 trial established neoadjuvant immune checkpoint inhibitor (ICI) therapy as a new standard of care, the pathological complete response (pCR) rate remains unsatisfactory at only 3.0%, highlighting an urgent need for optimized combination strategies. This prospective, single-arm, single-center clinical study aims to evaluate the safety, tolerability, and preliminary efficacy of a novel neoadjuvant and adjuvant regimen combining an engineered mitochondrial vaccine (IMP3-Mito) with ICIs for patients with resectable, IMP3-positive locally advanced HNSCC. The rationale is based on a "Prime-and-Release" synergistic mechanism: the engineered mitochondrial vaccine serves as a potent "natural adjuvant" to activate dendritic cells and prime tumor-specific T-cell responses against the IMP3 antigen, while the ICI subsequently releases the immune brakes within the tumor microenvironment. By integrating these two modalities, the study seeks to achieve deeper pathological responses and improve long-term survival, while simultaneously providing clinical evidence for the transformative potential of the mitochondrial engineering platform in overcoming the limitations of conventional tumor vaccines.
